Fin sections 351, whichare the component of a heat radiation unit 35 that will be describedlater, appear from the slits 32 a.

FIG. 4 is a bottom view of the computer according to the presentembodiment.

FIG. 4 shows the lower cover 32 that forms a case of the main unit 3together with the upper cover 31 (refer to FIG. 2). The lower cover 32is composed of a first panel 321, a second panel 322, a third panel 323,a fourth panel 324, and a peripheral panel 325. In the following, thefirst panel is typically taken up among these two or more panels and itexplains.

FIG. 5 and FIG. 6 are each a view showing the first panel. FIG. 5 showsthe appearance in which the first panel 321 shown in FIG. 4 is seen fromthe front side. The first panel 321 is provided with slits 321 e forventilation, and screw holes 321 a, 321 b, 321 c, and 321 d to installthe first panel 321 in a frame that will be described later. In thefollowing, for the sake of convenience of the explanation, among thescrew holes 321 a, 321 b, 321 c, and 321 d shown in FIG. 5, the screwhole in the vicinity of the center, the screw hole shown in the upperpart in FIG. 5 of the screw hole in the vicinity of the center, and thescrew hole in the right part in FIG. 5 of the screw hole in the vicinityof the center are referred to as a first screw hole 321 b, a secondscrew hole 321 c, and a third screw hole 321 d, respectively.

FIG. 6 shows a part of the first panel 321 in the state that the leftside of the first panel 321 shown in FIG. 5 is set up, and pushed downright, so that the first panel 321 is turned inside out. The third screwhole 321 d is shown left in FIG. 6, and the first screw hole 321 b isshown in right in FIG. 6.

In FIG. 6, bosses 320 are prepared for in surroundings of these thefirst screw hole 321 b and the third screw hole 321 d, respectively.Incidentally, the reason why the boss 320 is prepared for insurroundings of the screw hole is described later.

FIG. 7 is a view showing a state wherein the first panel is removed fromthe main unit.

FIG. 7 shows a shield 33 on which a circuit substrate equipped with CPUis mounted. The shield 33 is provided with a first locking hole 33 binto which a nut which is engaged with a screw on a spiral basis, thescrew being inserted through the first screw hole 321 b of the firstpanel 321 (refer to FIG. 5), is dropped, a second locking hole 33 c intowhich a nut which is engaged with a screw on a spiral basis, the screwbeing inserted through the second screw hole 321 c, is dropped, a thirdlocking hole 33 d into which a nut which is engaged with a screw on aspiral basis, the screw being inserted through the third screw hole 321d, is dropped, and a screw hole 33 e for substrate to install a circuitsubstrate equipped with an electric circuit in the shield 33. The screwhole 33 e for substrate to install a circuit substrate in the shield 33is installed at the position that shifts from the first locking hole 33b.

FIG. 7 further shows a heat radiation unit 35 which is composed of anendothermic board 353, a fin section 351 consisting of two or moreradiation fins, a heat transfer member 352 for transferring the heat ofthe endothermic board 353 through two or more radiation fins to the finsection 351, the heat transfer member 352 being installed in theendothermic board 353, and a fixing arm 354 for fixing the endothermicboard 353 on the circuit substrate equipped with CPU so that theendothermic board 353 is touched to the CPU.

FIG. 7 still further shows a fan 34 that sends air to a space formedwith the heat radiation fin of the heat radiation unit 35. The air sentfrom the fan 34 goes out of the slits 32 a shown in FIG. 3 too outsidethe case depriving of the heat that had conducted to the fin section 351when passing through the space formed with the heat radiation fin.

Here, there will be explained in detail the fin section 351 of the heatradiation unit 35 prepared for in the computer 1 according to thepresent embodiment.

FIG. 8 is a perspective view of a fin section.

FIG. 8 shows the fin section 351 penetrated with the heat transfermember 352, which is turned the side where air from the fan 34 flows outto the right of FIG. 8.

The fin section 351 shown in FIG. 8 is one in which first fins 3511 eachhaving a notch 351 a on the center portion of the air outflow side edge,and second fins 3512 each free from notch 351 a, are alternatelyarranged.

According to the present embodiment, the first fins 3511 and the secondfins 3512 are alternately arranged with spaces so as to spread width onthe air outflow side. As a result, it is possible to reduce thecollision of the edge of the first fins 3511 with air as compared with acase where only the second fins 3512 having no notch 351 a are arrangedsimilarly. Therefore, according to the present embodiment, thepreparation of the notches 351 a of the first fins 3511 on the edgeportion makes it possible to suppress the noise without so muchdecreasing the heat radiation function.

Incidentally, according to the present embodiment, the conduction ofheat to the fin section 351 is performed through the endothermic board353 and the heat transfer member 352. However, it is acceptable that thefin section 351 is disposed on CPU as not shown in the figure withoutthe endothermic board 353 and the heat transfer member 352.Alternatively, it is acceptable that neither the first fin 3511 nor thesecond fin 3512 are alternately arranged, but they are arrangedcalculatedly in such a way that the first one fin 3511 enters when thesecond two fins 3512 are consecutive.

FIG. 9 and FIG. 10 are each a perspective view of a fin section.

FIG. 9 shows a heat radiation unit 45 having a fin section 451 whereinsame notches 451 a as the notches 351 a explained in FIG. 8, areprepared only at the side where air of the first fin 4511 flows in,which is different from the fin section 351 shown in FIG. 8. In thisway, preparation of the notches 451 a only at the side where air flowsin also makes it possible to suppress the noise without so muchdecreasing the heat radiation function.

FIG. 10 shows a heat radiation unit 55 having a fin section 551 whereinsame notches 551 a as the notches 351 a explained in FIG. 8, areprepared at both the side where air of the first fin 5511 flows in andthe side where the air flows out. In this way, preparation of thenotches 551 a at both the side where air flows in and the side where airflows out makes it possible to further suppress the noise without somuch decreasing the heat radiation function.

Next, there will be explained the first locking hole 33 b, the secondlocking hole 33 c, the third locking hole 33 d, and the screw hole 33 efor substrate.

FIG. 11 and FIG. 12 are each a partially enlarged view of the frameshown in FIG. 7.

FIG. 11 shows the appearance in which the first locking hole 33 b, thethird locking hole 33 d, and the screw hole 33 e for substrate areprepared for in a thin thickness area 331 where it is dropped in by onestep so that the thickness is thinned more than other areas, of theshield 33.

FIG. 12 shows the appearance in which a circuit substrate 36 equippedwith CPU (not illustrated) that comes in contact with the endothermicboard 353 is screwed to the thin thickness area 331 of the shield 33through spacers 360. Also here, a position where the circuit substrate36 is screwed to the shield 33 shifts from a position of the secondlocking hole 33 c where the first panel 321 is screwed to the shield 33.

FIG. 12 further shows the appearance in which the fixing arm 354 isscrewed to the circuit substrate 36 through the spacers 360.Incidentally, the first screw hole 321 b on the back of the first panel321, and the boss 320 provided on the periphery of the third screw hole321 d, which are shown in FIG. 6, are for providing an offset for adifference of the groove formed with the thin thickness area 331 of theshield 33 and other areas so that the first panel 321 should not crackwhen tightening up a screw.

According to the present embodiment, the circuit substrate 36 and thefirst panel 321 are coupled with one another at positions which aredifferent with respect to the shield 33. Therefore, the impact to thefirst panel 321 is simply transmitted to the circuit substrate 36 onlyindirectly through the shield 33. Thus, according to the presentembodiment, it is possible to suppress the impact that the circuitsubstrate 36 receives as compared with the case where the circuitsubstrate 36 and the first panel 321 are screwed together in the samepart with respect to the shield 33.

Further, according to the present embodiment, the thin thickness area331 thins in its thickness through drop-in by one step from asurrounding area that is adjacent to the thin thickness area 331.Therefore, the thin thickness area 331 of the shield 33 and thesurrounding area serve as a damper, and thus it is possible to attenuatewith the shield 33 the impact that the first panel 321 receives. As aresult, the impact transmitted to the circuit substrate 36 through theshield 33 can be softened further more.

Next, there will be explained the structure of the image display unit 2in detail.

FIG. 13 is a view showing a computer wherein a frame cover of the imagedisplay unit is removed.

FIG. 13 shows the computer 1 wherein the frame cover 21, which coversthe front surroundings edge of the image display device 23, is removed,and the frame cover 21. Here, there is shown the appearance in which thewhole image display device 23 accommodated by the back cover 22 thatforms the case of the image display unit 2 with the frame cover 21 isexposed by detaching the frame cover 21. While the illustration isomitted in FIG. 13, actually, the camera unit, the mike unit, and thewiring etc. attached to these are furthermore disposed to surroundingsof the image display device 23. Moreover, though in the frame cover 21shown in FIG. 13, there is a part where acrylic board 26 is set in part,this is described later.

FIG. 14 is a view showing the inside of the back cover.

FIG. 14 shows the appearance in which the image display device 23 isdetached from the image display unit 2 in the state shown in FIG. 13,and the inside of the back cover 22 is exposed. Here, there is shown theappearance in which guide frames 24 that are vertically extended areinstalled at right and left both ends in the back cover 22,respectively.

The guide frames 24 are installed in the inside of the back cover 22 atintervals from standing walls 221 prepared for in surroundings of theback cover 22. The image display device 23 is set between these twoguide frames 24.

FIG. 14 further shows the appearance in which a wiring 100 passesthrough between the guide frame 24 shown at the right side in FIG. 14and the standing wall 221 of the back cover 22. Incidentally, actually,the wiring 100 passes through between the guide frame 24 shown at theleft side in FIG. 14 and the standing wall 221 of the back cover 22.This is omitted in illustration.

FIG. 15 and FIG. 16 are each an enlarged view of a guide frame.

FIG. 15 shows an enlarged view of the edge shown under FIG. 14, of theguide frame 24 shown left in FIG. 14, and also shows a hinge member 10.

The guide frame 24 is formed with an elastomer and fixed to theback cover 22 by a prescribed bonding means. The double-faced tape andthe adhesive can be adopted as the bonding means. Incidentally, it isacceptable that the guide frame 24 is composed of another part which isdifferent from the back cover 22 as in the present embodiment;alternatively, it is acceptable that the guide frame 24 is formed in aunited body with the back cover 22.

In the image display unit 2, the isolation section 243 of the guideframe 24 separates the image display device 23 and the wiring 100. Thus,according to the image display unit 2, the wiring 100 is prevented fromgoing into the space between the back of the image display device 23accommodated by the back cover 22 and the back cover 22. Therefore,according to the present embodiment, it is possible to prevent damage ofthe image display device 23 caused by the effect that the impact ontothe back cover 22 is transferred to the image display device 23 throughthe wiring 100 which goes into the space between the back of the imagedisplay device 23 and the back cover 22.

According to the present embodiment, it is possible to absorb thepressure that applies to the image display device 23 when the touchingsection 242 of the guide frame 24 is shaped as a convexo-concave.

According to the present embodiment, the dustproof of the image takinglens 251 is implemented in such a way that the seal material 27 isplaced between the acrylic board 26 and the barrel 252. This featuremakes it possible to contribute to a miniaturization in surroundings ofthe barrel 252 without decreasing dustproof as compared with a casewhere the cap that protrudes even to surroundings of the barrel 252 isinstalled. Incidentally, it is acceptable that the material of the sealmaterial 27 is a material because it only has to be able to securesealing up as soft as the sponge, but not the one limited to the hardrubber.

Although the present invention has been described with reference to theparticular illustrative embodiments, it is not to be restricted by thoseembodiments but only by the appended claims. It is to be appreciatedthat those skilled in the art can change or modify the embodimentswithout departing from the scope and sprit of the present invention.
